I've just reserved the new Miss Marple from the library, Murder at the Grand Alpine Hotel by Lucy Foley. I've been disappointed by some books that take a dead author's characters, but have read a couple of crackers recently so am going to give this one a whirl. I can also recommend Longbourn by Jo Baker, P&P below stairs and really well done, and The Golden Hours by Louisa Young, EJH's niece and a continuation of their own family history, The Cazalet Chronicles

A stylised image showing a red and white cable car agaunst a blue sky, above mountains with snowy caps. LUCY FOLEY is in white caps at the top, the Agatha Christie's signature, the the title MURDER AT THE GRAND ALPINE HOTEL in caps of mixed sizr and colour, red to gold.
A wonderfully 50s-60s pop art style cover to Louisa Young's The Golden Hours, reflecting the time it's set. Three vertical strips each featuring a linotype style image of a woman (three different women) facing a little differently, against background shades of orange, blue and yellow. The title is in large black caps bottom left, the author's name next to it in much smalletnred caps.
A painting style paperback cover of Longbourn by Jo Baker, showing a well-dressed woman in a cream dress, with her back to us, facing green panelling. To the right in the shadows a young servant girl faces us, looking away and down. She's holding a bucket. The title is in white caps, the author underneath in much smaller white caps.

Abstract: The CERN Large Hadron Collider will be upgraded to the High-Luminosity LHC, increasing the particle-collision rate and the demands on detector readout. A key element of this upgrade is the new CMS Tracker, whose silicon sensors will generate data at an aggregate rate of about 10 TB/s. This data must be routed efficiently to processing systems and filtered before storage. Serenity-S1 is an ATCA readout and data-processing card based on an AMD Virtex UltraScale VU13P FPGA with 128 high-speed serial transceivers. Twenty 12-channel Samtec FireFly optical modules provide up to 120 transmit and 120 receive channels at line rates of up to 25 Gb/s, while an additional optical module supports CMS Tracker links at up to 10 Gb/s per channel. The modular optical layout, combined with the large FPGA, makes Serenity-S1 suitable for several applications within and beyond CMS. ATCA provides the power and cooling required for operation in the CMS service cavern. Low-level management and the IPMI interface are provided by an OpenIPMC mezzanine, while an AMD Kria K26 system-on-module running AlmaLinux 9 performs higher-level board management and application control. Firmware and software frameworks provide common infrastructure so that users can focus on application-specific logic. The paper describes the hardware, firmware and software architecture of Serenity-S1 and its deployment in CMS Tracker integration and R&D activities.

I’m surprised there aren’t more lawsuits already.
“Texas abortion ban caused pregnant woman's death, lawsuit claims”
reuters.com/legal/government/t

Line chart labeled 12 deaths per million live births; in states without a ban it goes from 4 deaths in 2014 to 7.1 in 2025; in states with a strict abortion ban it goes from about 5 to 13.1. The chart includes the caption, “Deaths involving an ectopic pregnancy are grouped into three-year periods to meet data suppression thresholds. States with abortion bans that begin at six weeks of pregnancy or earlier are considered to have a strict ban. For the list of states in each group, see the methodo…

We expected rain (but no ⚡⛈️).
So we got our jackets, did our errands with our little bike trailer - and were lucky because it didn't even rain 💪
✅ Saved fuel again
✅ Physical activity
✅ Faster way to detach from work
✅ Saw a couple of cats
Totally recommended!

This image captures a cyclist riding a red bicycle on a paved path. The cyclist is wearing a blue jacket with a patterned design and a white helmet. Attached to the bicycle is a black trailer with a red cover, likely used for carrying gear or supplies. The path is bordered by a brick-paved driveway leading to a white house with blue shutters and a brown garage door. The house is surrounded by lush greenery, including trees and bushes, under a cloudy sky. description generated with Mistral.ai an…

The hallway started the day this meh grey-lilac colour, which had become very grubby and marked, and has ended it a nice invisible shade of mangolia. Next step is the stairwell and upstairs landing, maybe tomorrow otherwise next weekend. We'll be changing the pictures to show a few that have been in storage for years. All this because we needed to make good after having the new radiators fitted as part of the #HeatPump

A busy hallway painted in a sickly shade of lilacy-grey with white doors and skirting boards. There is a coat rack on the left corner between the front door and the loo, pictures on the wall and blue curtains in front of the door. There's a reddish shield on the wall that has no monetary value but did appear on Antiques Roadshow *checks notes* 42 years ago 😧
A hallway in a sickly shade of lilacy-grey with white doors, skirting boards and bannisters. The stairs go up on the left, carpeted in a deeply unexciting hard wearing oatmeal coloured material.
The same hallway now a nice clean shade of vanilla. I love it so uncluttered but some different pictures will go up, as will the curtains over the front door and the coat rack. The utility room is now a startlingly bright shade of green and the dining room is going to be a sage shade to complement my fabulous orange dining chairs, so I can live with a Dad-pleasing neutral shade in the hallway, up the stairs and on the landing.
